Subject: [patch 044/156] mm,hwpoison: unexport get_hwpoison_page and make it static
Date: Thu, 15 Oct 2020 19:43:34 -0700	[thread overview]
Message-ID: <20201016024334.n9jXNIPoi%akpm@linux-foundation.org> (raw)
In-Reply-To: <20201015192732.f448da14e9854c7cb7299956@linux-foundation.org>

From: Oscar Salvador <osalvador@suse.de>
Subject: mm,hwpoison: unexport get_hwpoison_page and make it static

Since get_hwpoison_page is only used in memory-failure code now, let us
un-export it and make it private to that code.
